To all whom "it may concern:

"Be it known "that I, JACOB II. Fnrnnnn- WALD, citizen of the United States, residing at Baltimore, Maryland, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

My invention is designed to provide a device for use with an internal combustion engine, so as to secure a perfect vaporization of the liquid hydrocarbon fuel with the proper quantity'of air, and I do this in a way so as to-secure a dry vapor.

My device perfectly mixes the gasolene and air, thereby converting the liquid hydrocarbon into a gas or elastic vapor.

I I secure great economy in fuel, and at the same time get the most perfect. results by combining the gas and air with a part removed; .Fig. 3 is a detail of one of the Vaporizers; and Fig. 4 is a sectional view of a modified form; Fig. 5 is a sectional detail view. In these drawings, a float chamber which may be of ordinary construction is shown at a, the float being shown at Z), and the valved inlet for gasolene at c. I provide in the chamber (Z a series of vaporizer-s, ten being shown in the plan View, though this number may be increased or diminished, ac-

cording to requirements, as I do not limit myself to the number shown. By means of these Vaporizers I secure a perfect mixture of the gasolene and air in the very best proportions for combustion and for economy of fuel. I prefer to utilize the construction of vaporizer shown in vertical section in Fig. 1,

and in horizontal section in Fig. 3, which is a section on the line a-c of Fig. 1, although I do not limit myself to the detail shown.

use a cap 6, of conical shape, and into the chamber formed by this cap I direct air pressure from a suitable source through theflpipe f, and the pressure of this air through "the orifice of the conical cap 6 creates a suction on the vertically ,dependin'g pipe 9 extending into the gasolene, and having an open the gasolene, and as the oil is drawn up andpasses out the open in such form as to make it perfectly combustible, and there- .upper end of the pipe g,

WlSl'l it to be understood devices that I find desirable, but

which is slightly below the opening in the cone e, it is vaporized and carried up with the jet of air into the cone h in the chamber The cone I: overhangs and covers the several Vaporizers of the series, it being understood that these are all alike, and that the description just given will apply to each one, and as they vapor of air and hydrocarbon passes upward into the cone h, it is thoroughly commingled, and as it passes down around the edge of the cone, it comes in contact with the links of the short chains is depending from the edge of the cone h, and is again broken up,- and thence passes out through the throttle to the combustion chamber. In order to still'further cause a commingling of the vapor, I may use a series ofslats shown .in Fig. 1 at Z, which may be set at any inclination. desired.

While I have descrlbed a Positive pressure on the pipes f through the a1r pipe m, I that I may utilize the draft from the engine instead of the forced draft to draw out the gasolene, and in this case I would simply make an opening in the top of the cone It so as to utilize the suction.

In Fig. 4 I utilize a series of cylinders 71, and locate within each cylinder a gasolene pipe g openat the bot-tom to the supply of gasolene, and utilize an air pipe f which joins the gasolene pipe, as shown, a slight distance below its upper end, so that the air pressure is directed upwardly through the air pipe, drawing with it its proportion of gasolene. Above the pipe 6 I use a deflector for breaking up the mixture, as at h, after which the mixture passes out through the pipe 0 into the vapor chamber p.

The vapor chamber 70 I protect from back fire by the valve or disk 1, which isnormally opened by the spring'r, but in case of back pressure, the force of the spring 1- is overcome, and the disk (1 is immediately forced against the seat 8, closing the entrance to theyapor chamber 79, and, at the same time, forcing open theIba-lls 25, which are sup- "ported upon the stem of the valve q, and opening passages for the discharge of the pressure and fire, and thus saving the vapor chamber from explosion.

I may not only use any number of spray I may provide for cutting one or more of them out in case I, find this necessary.

fuel is drawn. out to the point of vapriza-.

, moving in the cylinder is I sary VVh ile the suction caused by the piston sufficient to draw in the charge, I prefer,

drawings, to utilize the air pressure, and

thu'slighten'the work of the engine tothis extent. Wit-h my invention it isnot neces to prime or flood the carbureter, and indeed it is not possible for the carbureter to flood for the reason that thereis a positive fixed levellfor the gasolene. and the liquid tion by either the suction of the. engine on the one hand or the air pressure through the conical nozzle on the other.

In order that the mingling of the vapor in the cone it may be observed I prefer to make this cone of glass and also make of glass the sect-ion a".

What I claim is a 1.

a cone concentrically arranged within said mlxing chamber w1th its lower end extendas shown in the level, a cone'extendin ing over all of said plurality of cones; and a. plurality of chains depending from the edge of said upper cone, substantially as described.
